I am a Canadian on H1 status, and I am hoping to file my I-485 and I-140 concurrently in May. My H1 status is valid for 2.5 years after this point, as is my wife's H4. In the I-131 instructions it seems to suggest we can travel at any time while the I-485 is pending using my H1 status. Am I interpreting this correctly? Will we be able to travel abroad after filing the petition?
